So called "modern" wooden propellers are those manufactured after WW1, with the majority of them constructed before and after WW2. Many of these are still available new as certificated propellers for certified aircraft. In general, I believe they outnumber "early" propellers by a ratio of almost 10 to 1. They also lack the "character" of the early props, as they all have the same basic blade design. These sales occurred in 2011 or 2012, with the calendar dates noted.
